SPECIFIQATION forming part of Letters Patent No. 386,563, dated July 24,1888.

Application tiled December 7, 1887. Serial No. 257,202. (No model.)

To @ZZ w/'Lom if may concern:

Be itknownthat l, JOHN A. STEELE, of Minneapolis, in the county ofHennepin and State of Minnesota, have invented certain Improvements inTents, of which the following is a specification.

My invention relates to the construction of the pole of a tent,whereby Iam enabled to use a portion of it for a tlue or chimney and avoid theliability of burning or scorching the canvas; and it consists,generally, in the construction and combination hereinafter described,andparticularly pointed out in the claims.

In the drawings which form a part of this specication, Figure l is aside elevation and partial section ot' atent, showing my improvementapplied thereto. Fig. 2isa section showing a modification in theconstruction of the tent. Fig. 3 is a section ot' a portion of the poleembodying my improvement, and Fig. 4

is a detail.

In the drawings, 2 represents a tent, which may be of the style commonlyknown as a wall-tent,77 as shown in Fig. l; or it maybe the style knownas a Sibley,7 as shown in Fig. 2.

In the style shown in Fig. l the tent is supplied with the two end polesorsupports, 4,and the ridge-pole 6, which form a frame, over which thecanvas covering of the tent is secured. One ot' the end poles 4 isshortened at the top and a hollow metallic pipe or tlue, 8, is placedupon it, the lower end of the said pipe forming a socket, into which thepole is securely fastened, the pipe thus making a continuation of thesaid pole, which extends to any desired distance above the ridge-pole 6.An outer casing, 10, is placed around the pipe 8, and preferably extendsfrom the point of intersection with the ridge-pole 6 downward a suitabledistance within the tent, and this casing may be securely braced andfastened to the pipe 8 by thimbles l2, placed at' intervals around thepipe between it and the casing,and having bolts passing through them andthrough the walls of the said pipe and secured by suitable nuts on thesaid bolts. Other devices may be used forsecuring the casingto the pipewithout departing from my invention.

A branch pipe, 14, is preferably connected with the pipe S at a shortdistance above the end of the pole 41. This pipe passes through anopening in the casing l() at the side toward the interior of the tent,and is connected by means of suitable elbows and pipe with the stove 16.

I prefer to connect the ridge-pole 6 to the casing in such a manner thatit can be easily Vdisconnected when the tentis taken down. A yoke orclamp, 1S, is secured to the outer casing, 10, and provided withinwardly-projecting flanges 20 upon the two sides and a stop or rest,22, at the bottom, forming a recess open at the top between thesaidlianges, into which the outwardly-flanged end support, 24,secured uponthe ridge-pole, is inserted from the open top and rests upon the stop22.

As the force exerted upon the ridge-pole when the tent is in positionwill always bein a downward direction, the said pole and casing will besecurely and firmly held in their proper position. A support, 2G, may beplaced upon the outer surface ot' the casing 10, opposite the pointwhere the ridge-pole is joined, in order to support the peak of thetent. A hole is cut in the canvas sufficiently large to receive thecasing 10, and the peak will then rest upon the ridge-pole G upon oneside of the casing and upon the support 26 upon the other, allowing thesaid casing to project through the upper portion of the tent andcommunicate with the open air. The end wall or Hy, 2S, extends down fromthe support 26 and forms a covering for this portion of the tent, and isprotected from coming in contact with the heated due-8 by the casing l0,which forms an interposing air-space between the said pipeand thecanvas. The heated surface of thepipe S will cause an upward draft orpassage of ai r through this space and prevent the heating of the saidouter case, and at the same time furnish a means of ventilation for theinterior ofthe tent, and a firm support is made for the stove-pipe.

The stove pipe which I prefer to use is formed in sections, as 30, 32,and 34. Each section is made slightly cone-shaped. The lower sectionprojects into the section above, this section into the next, and so on,and the elbow 36 is secured to the upper section and to the branch pipe14.. \Vhen itis desired to take down and pack the pipe, the section 32can be placed inside the section 30 andthe section 34 IOO inside thesection 82. This enables me to closely pack the pipe.

Any number of sections can be used,and will take up no more room inpacking than a singie section. By providing the firm support made by thepipe 8, secured to the pole, as described, I hold the pipe as firmly andsecurely as in any ordinary stove, and without liability of beingdisplaced or being blown down, as is the case when the pipe is extendedthrough the canvas of the tent.

In Fig. 2 I have shown a modilication of my improvement as adapted foruse in a Sibley tent. In this construction, as there are no end walls toprotect and no ridge-pole to attach, I am enabled to shorten the outercasing, making it simply a ring for the protection of the canvas, towhich the said canvas is secured. In other respects it is substantiallysimilar to that already described.

What I claim is- 1. In a tent, the combination, with the upright pole 4,of the pipe 8, secured to said pole, the outer casing, 10, secured toand surrounding the pipe 8 and forming an interposed airspace betweensaid pipe and the canvas covering of the tent, substantially asdescribed.

2. In a tent, the combination, with the upright pole 4, of the pipe 8,secured to the said pole, the outer casing, l0, secured to andsurrounding the pipe 8 and forming an interposed air-space between saidpipe and the canvas covering of the tent, and the ridge-pole 6, securedto said casing 10, substantially as Adescribed. .i

3. In a tent, the combination, with the pole 4 and the pipe 8, securedthereto, the outer casing, l0, surrounding said pipe, and the ridge-pole6, secured to said casing 10, of the branch pipe 14, connected to thepipe 8, the elbow 36, and the sections of pipe secured thereto orarranged to be placed one inside the other, substantially as described.

In testimony whereof I have hereunto set my hand this 2d day ofDecember, 1887.

JOHN A. STEELE.
